[0030] Example 1

[0031] Reference Figures 1-5 This embodiment provides a CNC milling machine that facilitates chip removal, including a CNC machining assembly 100. The CNC machining assembly 100 includes a CNC milling machine body 101. A machining head 101b is installed at the center of the surface of the CNC milling machine body 101. A machining base 101a is fixedly connected to the bottom of the inner cavity of the CNC milling machine body 101. A storage box 101c is connected to the bottom of the inner cavity of the CNC milling machine body 101. A fixing block 101d is fixedly connected to the inner wall of the CNC milling machine body 101. An electromagnet 101d-1 is fixedly embedded in the top of the fixing block 101d.

[0032] Furthermore, there are four fixing blocks 101d, and a sealing baffle 101c-1 is movably installed on the surface of the storage box 101c.

[0033] It also includes a miscellaneous removal component 200, which is installed through the inner cavity of the CNC milling machine body 101. The miscellaneous removal component 200 includes a movable cylinder 201 and a motor 202. An exhaust hole 201a is provided through the bottom of the inner cavity of the movable cylinder 201. A positioning rod 201c, a hollow sleeve 201b, a positioning rod 201c and a storage shell 201d are respectively installed at the front and rear ends of the movable cylinder 201. A positioning sleeve 201c-1 is movably fitted on the surface of the positioning rod 201c. A displacement sleeve 201c-1a is fixedly connected to the bottom of the positioning sleeve 201c-1. A gear 201d-1 and a magnetic rack 201d-2 are respectively installed inside the storage shell 201d. A lead screw 202a is fixedly connected to the output end of the motor 202.

[0034] Furthermore, the left side of the motor 202 is fixedly mounted on the CNC milling machine body 101 by bolts, and the left end of the lead screw 202a passes through the displacement sleeve 201c-1a and is threadedly connected to the displacement sleeve 201c-1a.

[0035] Furthermore, there are several exhaust holes 201a, which are evenly distributed on the movable cylinder 201, and the exhaust holes 201a are set at an angle.

[0036] Furthermore, the front end of the hollow sleeve 201b is connected to the inner cavity of the movable cylinder 201, and the rear end of the hollow sleeve 201b is connected to an external air pump through a telescopic hose.

[0037] Furthermore, there are two positioning sleeves 201c-1, which are respectively fitted onto the hollow sleeve 201b and the positioning rod 201c.

[0038] Furthermore, the connection between the hollow sleeve 201b and the positioning sleeve 201c-1, and the connection between the positioning rod 201c and the positioning sleeve 201c-1, are all connected by damping bearings.

[0039] Furthermore, the inner ring of gear 201d-1 is movably connected to the connection of movable cylinder 201, and magnetic rack 201d-2 is slidably mounted on storage shell 201d.

[0040] Furthermore, gear 201d-1 meshes with magnetic rack 201d-2, and the surface of housing 201d is fixedly connected to the connection point of positioning sleeve 201c-1.

[0041] Furthermore, the movable cylinder 201 is located on top of the machining base 101a, and the bottom end of the magnetic rack 201d-2 is equipped with a magnet.

[0042] It should be noted that a crossbar is fixedly connected to the rear side of the inner cavity of the CNC milling machine body 101. The crossbar passes through the displacement sleeve 201c-1a on the rear side and slides in contact with the displacement sleeve 201c-1a. This design can effectively improve the left and right displacement stability of the positioning sleeve 201c-1, the displacement sleeve 201c-1a and the movable cylinder 201.

[0043] The CNC milling machine body 101 is equipped with a controller, and the motor 202 and electromagnet 101d-1 are both electrically connected to the controller;

[0044] By setting up a storage box 101c and a sealing baffle 101c-1, the storage box 101c can store the blown debris at a low position, preventing the debris from escaping at will. Furthermore, with the sealing baffle 101c-1 open, it is convenient for workers to clean the inside of the storage box 101c in a concentrated manner. The fixing block 101d can meet the fixed installation requirements of the electromagnet 101d-1. By setting up the electromagnet 101d-1 and the magnetic rack 201d-2, the electromagnet 101d-1 generates magnetic force when energized, which in turn generates magnetic repulsion or attraction at the magnetic bottom end of the magnetic rack 201d-2. The exhaust port 201a can disperse the airflow for uniform cleaning of the bottom of the CNC milling machine body 101. The device features a hollow sleeve 201b that connects to an external air pump via a flexible hose. When the air pump is operational, gas can be introduced into the movable cylinder 201. A displacement sleeve 201c-1a and a lead screw 202a provide threaded transmission. Driven by a motor 202, the lead screw 202a rotates continuously, causing the displacement sleeve 201c-1a to move left and right. A storage shell 201d provides storage space for the gear 201d-1 and the magnetic rack 201d-2. These gears engage in a meshing transmission; when the magnetic rack 201d-2 moves up and down, the gear 201d-1 rotates in both directions.

[0045] During use, all components are in their initial installation state. To avoid the movable cylinder 201 affecting the normal processing of the workpiece, the movable cylinder 201 should initially be located on the inner side of the CNC milling machine body 101. When chip removal and cleaning are required, the control motor 202 drives the lead screw 202a to rotate. With the cooperation of the displacement sleeve 201c-1a, the positioning sleeve 201c-1, the receiving shell 201d, and the movable cylinder 201 move to the right synchronously. At the same time, the external air pump operates to pump air from the hollow sleeve 201b. The debris is introduced into the movable cylinder 201 and finally ejected through the inclined exhaust port 201a, gradually pushing the debris into the storage box 101c for temporary storage, thus completing the blow-type cleaning. In actual use, when the movable cylinder 201 is to be moved to the right for cleaning, the exhaust port 201a should be at an angle tilted downwards and to the right to facilitate good blowing and cleaning of the debris. First, the drive motor 202 is activated to adjust the storage shell 201d above the fixed block 101d on the left. Then, the corresponding electromagnet 101d-1 is energized, and... The magnetic rack 201d-2, with its bottom magnet engaging, generates a magnetic attraction force, causing it to automatically move downwards and engage with the electromagnet 101d-1. Under this meshing transmission, the gear 201d-1 rotates counterclockwise, driving the positioning rod 201c, the movable cylinder 201, and the hollow sleeve 201b to rotate. This adjusts the exhaust port 201a to an angled downwards and to the right, meeting the rightward blowing cleaning requirement. Specifically, when the magnetic rack 201d-2 is in its protruding state, the exhaust port 201a is angled downwards and to the right. Similarly... When the magnetic rack 201d-2 is placed on the electromagnet 101d-1 on the right side, the electromagnet 101d-1 is energized and generates a magnetic repulsion force on the magnet on the magnetic rack 201d-2. The magnetic rack 201d-2 will gradually move upward, and the gear 201d-1 will rotate clockwise. The exhaust port 201a is adjusted to tilt downward and to the left to meet the cleaning requirements of the exhaust port 201a for blowing debris when the movable cylinder 201 moves to the left. That is, when the magnetic rack 201d-2 is in the state of protruding top, the exhaust port 201a is tilted downward and to the left.

[0046] In summary, by setting up the storage box 101c, the fixing block 101d, the electromagnet 101d-1, and the debris removal component 200, the motor 202 can be controlled to drive the lead screw 202a to rotate, thereby causing the movable cylinder 201 to move left and right. High-speed gas is ejected from the exhaust port 201a to clean the debris at the bottom of the CNC milling machine body 101. Finally, the waste is temporarily collected in the storage box 101c, making it convenient for staff to clean it up.
